Summary: The major task of Chinese water governance has shifted towards water ecology remediation and the governance of trace organic pollutants, such as persistent organic pollutants (POPs) and antibiotics, is of growing concern. This study investigated the seasonal distribution and sources of typical POPs and antibiotics in six representative water sources in the lower reaches of the Yangtze River, as well as their ecological risk. The results showed that POPs were detected in sediments from Gaoyou Lake, Gonghu Lake, and Gehu Lake, while antibiotics were present at relatively low levels in the water sources. Certain ecological risks were identified in water sources affected by POPs, whereas the overall risk level was moderate for antibiotics in Lake Gehu. This study provides valuable insights for the treatment of antibiotics and organic pollutants in reservoir water sources.

Summary: Exposure to legacy and emerging persistent organic pollutants (POPs) poses a significant threat to individual health, with implications for neurodevelopment, endocrine function, and cardiovascular homeostasis. Although the association between traditional air pollutants, exercise, and lung function has been extensively studied, there is a lack of reviews on the relationship between POPs and exercise. This literature review examines the impact of exercise on exposure to POPs, health risk assessment, and the redistribution, metabolism, and excretion of POPs in the body. The review highlights the various benefits of exercise, such as improved insulin sensitivity, mitochondrial DNA repair, lipid metabolism, and intestinal microecological balance. Furthermore, individual lipid metabolism status plays a crucial role in evaluating the potential link between exercise, POPs, and health effects.

Summary: This article suggests that the safe operating space of the planetary boundary for novel entities is exceeded due to the increasing production and releases exceeding the global capacity for assessment and monitoring. Plastic pollution is highlighted as a major concern. The article presents an impact pathway from the production of novel entities to their impacts on Earth system processes and proposes several criteria for control variables. Urgent action is recommended to reduce the harm associated with exceeding the boundary by reducing the production and releases of novel entities.

Summary: Persistent organic pollutants (POPs) have accumulated in polar environments due to long-range transport. Climate change has been identified as a factor influencing POP levels and trends, and recent studies have found correlations between climate indices and POP temporal trends. Temperature, precipitation, and sea-ice have also been recognized as important climate parameters affecting POP levels. However, the complexity of physical, chemical, and biological processes requires greater interdisciplinary scientific exchange and collaboration.

Summary: A study found relatively high concentrations of chlorinated paraffins (CPs) in moose from Grimso'', Sweden compared to other wildlife in Scandinavia. The study examined the temporal trends of CP concentrations in moose calves over the past 40 years. The results showed increasing CP concentrations from 1982 to the 1990s, high levels in 1993 and 2008, and decreasing concentrations after 2012. Male moose had exponentially increasing CP levels with age, while females had exponentially decreasing CP levels. The accumulation of CPs in moose suggests additional stress on males of this long-lived terrestrial mammal.

Summary: Increased demand for recycling plastic has raised concerns about the potential introduction of hazardous chemicals. A comprehensive screening of 21 plastic flake and pellet samples from Canadian recycling companies revealed the high detection frequencies and concentrations of organophosphorus ester flame retardants and plasticizers, suggesting their incorporation into recycled goods. Although individual concentrations met European Union threshold limits for recycled granules and waste plastic flakes, further research is needed to determine their toxicological thresholds. Our study emphasizes the importance of additional screening to fully understand the presence of potentially hazardous chemicals in goods made from recycled plastics.

Summary: Fluorine mass balance studies in municipal wastewater treatment plant (WWTP) sludge showed that conventional per- and polyfluoroalkyl substances (PFAS) account for only a small fraction (approximately 2%) of the extractable organic fluorine (EOF). The remaining EOF, which includes fluorine-containing pharmaceuticals and pesticides, was identified using high resolution mass spectrometry-based suspect screening. The presence of various pharmaceutical substances, pesticides, and conventional PFAS was confirmed, expanding the known EOF percentage from 2% to 27%. These findings highlight the importance of considering unconventional and non-PFAS organofluorine substances in addition to conventional PFAS when assessing the organofluorine mass balance in WWTP sludge.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.
